Welcome to the Resident Evil 4 Chapter 10 Collectibles guide for the 2023 remake. This guide will walk you through where to find all 7 treasures and the clockwork castellan in Chapter 10 while navigating the Castle. During your first playthrough, make sure you trade with the merchant for each region’s map to simplify gathering treasures.
This guide shows the treasures found in the base game and does not include the extra treasures unlocked with the Deluxe Edition of the game. Those treasures are always shown on the map and are either found in chests or in lanterns hanging from trees/ceilings.
Please refer to the Resident Evil 4 Achievements Guide for details about all achievement/trophies in the 2023 remake.
